drilling holes in al. seatpost?

[Weight Weenie]

Saw these spesh ones in tread a while back, but does any company make something like that for 31,6mm posts ?

 

Profile designs also have some interesting stuff and cyclelab in centurion ha some other gizmo with a sort of zip tie fastener that you could mount cages to

[Weight Weenie]

Oh and try the giant bottels for the back and bottom, they have a lid that clicks on and covers the mouth piece.  Works very well in muddy conditions.  you can get them at sportsmans warehouse, about R25.

I like those specialized clamps...nice idea. anyone seen any in a shop in cape town?

 

 

 

I dont mind a camelbak - I have used one for a long time, but I get hot so extra heat build up because of lack of ventilation - not major but definitely an issue.

Speak to a surgeon who specialises in colon surgery and have him tell you about the consequences of sharp objects penetrating down there. Please don't drill your seatpost.

 

I bet a bit of silicone sealant and two big cable ties will clamp a standard bottle cage perfectly well.

I got mine @ Olympic. I suppose most shops that stock Specialized will have them.

Glad you answered...... seatposts with deep scratches can also induce a failure on the scratch.... very much like the scratch you make on glass to break it. These scratches can come form when you try to extract a slightly stuck seatpost.

 

If you drill also pace a red arrow with the marking "break here" on the seatpost.

some of us are looking for 31.6...I'll maybe give 'em a call tomorrow...

[Weight Weenie]

hth

[brussel]

soltice is that R130 for the pair? or for one?

 

 

 

anyone use the zefal ones? not sure how good they would be compared to the machined specialized ones.

[Weight Weenie]

Ill try some of the zefal one sometime, I can carry 2 bottles in my frame but it's not enough for longer races with crappy water points, rather take more drinks with.

[100Tours]

I used to ride with a plastic bottle cage fixed to the seatpost with 2 zipties, and cushioned with a length of double sided tape. Worked great. Cost R40.

[AndreZA]

Dunkeld cycles also has the Spez ones. Did not see price but saw it on the rack last week.

[Solstice]

R130 for the pair...

[Renier82]

im also a armgat... would also use 2 fat cable ties and some duct tape and make the sucker stick... or 2 stainless/galvanised hose clamps and tighten it well. you guys are too fancy for me ;-)
